BEARIN G CONSTRUCTION.

Application filed September 5, 1924. Serial 110. 785,982.

To all whom it may concem;

Be it known that I, ELY" G. HU'rcHI soN, a citizen of the United States, residing at city and county of San Francisco, and State of California, have invented certain new and useful Improvements in Bearing Construction, of which the following is a specification. 1

The present invention relatesto bearing construction and particularly to bearings supporting shafts in either horizontal or vertlcal'positions. Heretofore, bearings of this nature have been made of lignum vitae, with or without means for adjustment to take u wear. To make this type of bearings a justable involves heavy expense and a complication of parts which it is very desirable to remove. a

The object of the present'invention is to produce an inexpenslve adjustable bearing which contains wearing elements that are easily removed and re laced and upon which the adjustment may out retarding or stopping the rotation of the shaft and without fear of tightening the bearin to such an extent as would cause disaster t rough overheating.

Another object is to provide a means whereby said bearing may be lubricated at all times when the shaft is in operation.

With the above mentioned and other objects in view,'the invention consists in the novel construction and combination of parts hereinafter described and illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in form, proportion, size and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advanta s of the invention.

0 more fully comprehend the invention, reference is' directed to the accompanying drawings, wherein-- Fi 1 is a longitudinal section of a preferre embodiment of the invention taken on line 11 of Fig.2.-

Fi 2 is a cross section of same taken on the line 2-2 of Fig. 1. I

Fig. 3 is a fragmentary perspective view of one of the bearin rin s. V In the drawings wherein like characters of reference designate corresponding parts, 1

e accomplished with- 'means for the metal indicates a shaft, provided on its outer surface with a bronze sleeve 2. Said shaft is mounted within and bears upon a series of The rings may be moulded solid or scarfed on the ends.

due to their s 'dability provide a means I whereby the bearing rings 3 may be adj ustedi by exerting a compressive force paralle with the shaft axis. 5, are gland members at the top and bottom of the bearin which serve as retaining heads for the caring rings 3 and the slidable metal containers 4,

holding the same in position.

Said glands and the packin 6 thus form compressin earing'rin and are held in position by containers grooved on their baoksas, shown at 4:. packing rings 3 and the metal containers 4, which comprise the bearing, are fitted within a bearing seat 8 preferably made in section means of t e nuts 7- 11? are circumferential'ly" The as shown in Fig. 2 and clamped together by bolts 13. The bearing seat 8 is provided with opposite longitudinal chambers, one of which '9 is connected at its top as at 10 with a source of water, or other lubricant not shown, under pressure, and the other 9 'communicates at its bottom with a discharge 10'. These chambers are to provide a lubricating means for the bearing, the lubricant passing from the su ply chamber 9 through the ports 11 in t e wall of the seat 8 into the ack grooves 4' of the'metal chambers 4 and thence through ports 4" in the s acing portion .of said containers to the ace of the bearing rings 3,in which rin water assage ooves 3" are made as s own in 3.- T e water so admitted is discharged at the opposite side of the bearing throu h the corresponding orts and grooves, in lcated like numera 8. into the charge chamber re, as shown in Fig. 1, relative y staggered so that alternate members on each si efmaly carry them and thus have the lubricant reac The ports 11 and 4" on o posite sides all parts of the bearing. The lubricant is disc arged from the bea and" from thedischarge chamber into a co lector 12.

I claim:

1. A shaft bearing comprising a plurality of compressible bearing rings embracing the shaft; a series of slidable DOIl-COIDPI'QSSlblG' rings separating and surrounding a portion of the bearing) rings.

of the width of said bearing rings; means applied to the end of the series of slidable rings for exerting pressure thereon to adjust the compressible bearing rings to theshaft and means for supplying a lubricant under pressure to the face of the bearing-rings con sisting of a supply chamber in one side of said hearingJ1 connected with a source of lubricant, 'a scharge chamber on the opposite side of said bearing for discharging the lubricant and suitable channels from said chambers communicating with the face 2. A shaft caring comprising a plurality of compressible bearing rmgs'embracing the shaft; a'series of slidable non-compressible rings separatin and surrounding a portion of the width o said bearing rings; means applied to the end of the series of slidable" rings for exerting pressure thereon to adjust the compressible bearing rings to the shaft; and means for supplying a lubricant through the said'slidable rings to the face of the bearing rings consistingof a supply chamber in one side of said bearing connected with a source of lubricant, a discharge chamber on the opposite side of said bearingfor discharging the lubricant and suitable chan-' nels from said chambers communicatin with the face of the bearing rings, sai channels being relatively staggered with relation to the opposing chambers.

' I 3. A shaft vbearing comprising a plurality,

of compressiblebearing rings embracing the shaft; a series of slidable non-compressible rings separating said bearing rings; a fixed bearing seat embracing an guiding slidable rings;-means applied to the end of the series of said slidable rings for exerting pressure thereon to ad'ust the compressible earm supplying a lubricant under pressure to the rings. to the aft; and means for face of the bearingrings consisting of a supply chamber in one side of said bearing seat connected with a source of lubricant, s8 discharge chamber onthe opposite side of said bearing seat for discharging the lubricant and suitable channels from said chambers communicating with the face of the hearing A rlngs.

4. A shaft bearing comprisinga plurality of compressible bearing rmgs embracing the'f shaft; a series of slidable non-compressible rings separating said bearin rings; a fixed bearing seat embracing an guidin said slidable rings; and means applied to t e end able non-compressible rings separatin said of the series of said slidablerin for exerting pressure thereon to adjust t e compressible bearing rings to the shaft; and means for supplying a lubricant under pressure to the face of the bearing rings consisting of a supply chamber in one side of said bearing seat connected with a source of lubricant, a discharge chamber on the opposite side of said bearing seat for discharging the lubricant and suitable channels from said chambers communicating with the face of the,

bearing rings, said channels being relatively staggered with relation to the opposing chambers. I

, 5. A shaft bearing comprising a plurality of compressible bearing rings embracing the shaft, a series of slidable non-compressible bearing rings separating said compressing bearing rings with the o posing edges of the respective compressib e bearing rings contacting with successive non-compressible bearing rings, means applied to the ends of the seriesof said slidable rings for exerting pressure thereon to adjust the compressing with the grooves of alternate non-compressible rings; v

6. A shaft bearing comprising a plurality of compressible bearing rings embracing the shaft, said rings on their lnner face being grooved from top to bottom, a series of slidand surrounding a portion of the width 0 said bearin rings, means applied to the end of the series of slidable'rings for exerting ressure thereon to adjust the compressible earing rings to the shaft, and means for supplying a lubricant through the said slidab rings to the grooved face of the bearing rings" consisting of a supply chamber in one side of said bearing connected with a source of lubricant, a discharge chamber on the opposite side of said bearing for discharging the lubricant and suitable channels from said chambers comunicating with the face of i the bearing rings, said channels being'relatively staggered with relation to-the opposing chambers;
